FORGING Application filed May 2,

This invention relates to forging machines and more especially thoughnot exclusively to that type of forging machine used for forging drillsteels or similar tools.

One object of the present invention is to provide an improved forgingmachine. Another objeet of the present invention is to provide acompact,light machine having a minimum number of projecting parts, and onehaving also an improved clamping mechanism for holding a tool during theupsetting operations thereon. These and other objects and advantages ofmy improved construction will, however, hereinafter appear.

In the accompanying drawings, I have shown for purposes of illustrationone embodiment which my invention may assume in practice. 7 v

In these drawings,

Fig. 1 is a longitudinal sectional view sub-' stantially on the line 11,Fig. 2, of my improved forging machine parts thereof being shown in sideelevation.

Fig.2 is a longitudinal sectional'view substantially on the line 2-2 ofFig. 1, part of the forging machine being shown in side elevation.

In this illustrative construction I have I shown a hollow base orcasting 1 carrying a swaging mechanism 2 and an upsetting mechanism 3,the latter being adapted to actuate a dolly a to upset the endof'thesteel held fixedly between a fixed jaw 5 and a movable jaw or head 6 ofan improved The fixed jaw 5 of his clamping mechanism is preferablyinclined at an acute angle, herein to the horizontal to provide aslanting face 7on which a steel may be guided into a die 8 carried bythis jaw, this fixed jaw 5 being also preferably slanted as stated aboveso that when the movable jaw 6 is moved away therefrom, a free openingis provided at one side of the swaging mechanism 2 to permit theinsertion of a steel between the vise It will be noted that by havingthe face 7 slanting the die 8 will have a suflicient amount ofsubstantially horizontal surface so that a steel can rest thereonwithout additional aid. The movable vise jaw 6 carries a mating die 9,it being understood that the steel to be upset is firmly clamped betweenthe dies'S and 9 during the upsetting operation. The base 1 and themovable jaw 6 are herein shown MACHINE;

struments'than the swaging or upsetting mechanisms. However, it isunderstood that the clamping members 10 and 11 may be removed and a pairof shearing members substituted therefor, if it is desired to use the.mechanism for cutting off the end of stock. I

The movable j aw'6may be operated in a variety of ways but in thepreferred form of my invention, I have shown a controlling lever 12preferably formed integral with the jaw 6, the lever and jaw beingpivotally mounted on a stud shaft 13 carried by the frame, and the head6 being rotatable through amovement of this lever to clamp a toolbetween either pair of jaws. In the form of actuating means for thelever shown herein, I have provided a relatively large cylinder 14 inwhich is reciprocably mounted a large piston head 15 provided with aforwardly extending portion 16. The upper part of the large piston orportion 16 preferably carries in a recess 17 formed-therein a link- 18pivotally connected, as shown at 19, to the piston rod and pivotallyconnected, as'shown at 20, to the lever.

If desired, the cylinder 14 may be of the 7 double acting type havingprovision for admitting fluid pressure to both sides of the piston head15 to move the latter in either direction, but I preferably admitpressure fluid to but one face of the piston head 15 to nove the pistonto the right (see Fig. 1) and for this purpose, I provide an inlet pipe-21 for conducting pressure fluid to the rear end of the cylinder 15, theflow to this end being controlled by suitable valve mechanism, notshown, preferably placed in the hollow base or casting 1. To provide fora return movement of the piston, I preferably form a cylinder chamber 22in the large piston rod 16 and place in this cylinder a fixed hollowpiston rod 23 having a passageway 24 preferably provided axiallytherein, and, connected with an inlet pipe 25 which is preferablyconstantly supplied with live pressure fluid which acts on the oppositefaces 26, 27 of the cylinder 22 and piston rod 23, respectively, andtends to force the piston rod 16 to theleft and norinallyretain theclamping members 10 and ill) til)

' distance beyond the base 1.

It will thus be seen that I have provided an exceedingly compact andlight forging machine and that I have provided an improved clampingmechanism into which a steel. is easily insert-able, and further, that lhave provided means for uiding the steel,

during the insertion tl ercof between the dies held by the respectivevise jaws. It will also be noted that a very powerful clamping means isproviued which exceedingly light and may be easily and cheaply manufaotured and which is easily controlled through the control of a simplevalve mechanism in the base of the machine, and that one pair ofclamping members is normally retained in clamping position.

While I have in this application specifically described one embodimentwhich my invention. may assume in practice, it is to be understood thatthis form is used for illustrative purposes only and that the inventionmay be modified and embodied in various other forms without departingfrom its spirit or the scope of the appended claims.
